Why Finance MattersRoughly half the adults in the world, about 2.5 billion people, have no bank account nor even access to a ―semi-formal‖ financial service like microcredit. But what if they did? Muhammad Yunus, the 2006 Nobel Peace Prize winner and founder of Bangladesh’s Grameen Bank, argues that this lack of financial access means that the poor, especially poor women, can’t obtain the tiny loans (known as microcredit) that they need to build their businesses and get on a path out of poverty. The idea has taken hold: in 2009 Grameen Bank served 8 million customers (the average loan balance was just $127). World-wide, microcredit advocates claim over 190 million customers.
